Cannot keep to promises.

In sept 2014 i was called up by Vodacom to do a migration to a better deal. I asked will i be charged more and they said no. <br> <br> 4 months later i realised that i have been paying more. Feb came i called up to revert to my old package. i was advised this will take 5 working days.<br> <br> <br> 2 months went by and i never heard from them again. only at the end of april a Opt manager took ownership and fixed everything for me making sure i was getting my money back. once the payment date came and every thing was debited correctly i was promised by eric that he will call me back the next day and today i am still waiting for the next call for compensation. i have been waiting from the 28th April ...<br> <br> i called again two days ago, once again promised a call back and i am still waiting.<br> <br> <br> all i want is compensatition for the way my query has been dealt with.
